Definitions
- the present invention relates to vehicle braking, and more particularly to a regenerative braking system for a vehicle.
- Some internal combustion engines include engine control systems that deactivate one or more cylinders under low load situations. For example, an eight cylinder engine can be operated using four cylinders to improve fuel economy by reducing pumping losses. This process is generally referred to as displacement on demand (DOD) or cylinder deactivation.
- DOD displacement on demand
- Electric hybrid vehicles include an engine and at least one electric machine.
- the electric machine draws current from the battery and powers the vehicle alone or in combination with the engine.
- the electric machine operates in a generator mode and assists braking by absorbing kinetic energy of the vehicle to slow vehicle motion.
- the generator converts the absorbed kinetic energy to current, which is used to recharge the battery. This process is commonly referred to regenerative braking.
- regenerative braking can be implemented when the vehicle is powered by the engine and/or the electric motor at the time of braking.
- current that is produced by regenerative braking has been limited by engine braking.
- the engine slows the vehicle by absorbing some of the kinetic energy of the vehicle. As a result, less kinetic energy is absorbed through the regenerative braking, which reduces current generation.
- the present invention provides a regenerative braking system for a vehicle.
- the regenerative braking system includes a displacement on demand (DOD) engine having cylinders, a battery, and an electric machine having motor and generator modes.
- the electric machine is selectively driven by a wheel of the vehicle.
- a controller detects a braking condition of the vehicle and deactivates at least one of the cylinders in response to the braking condition.
- the controller operates the electric machine in the generator mode during the braking condition to charge the battery.
- DOD displacement on demand
- the controller deactivates one of the cylinders of the engine in response to the braking condition.
- the controller detects termination of the braking condition and activates at least one of the cylinders in response.
- the controller selectively operates the electric machine in the motor mode to drive the wheel.
- the controller selectively deactivates all of the cylinders of the engine and operates the electric machine in the motor mode to drive the wheel.
- the electric machine charges the battery when operating in the generator mode.
- FIG. 1 is a functional block diagram of a hybrid vehicle including a DOD engine and a regenerative braking system
- FIG. 2 is a flowchart illustrating steps performed by the regenerative braking system according to the present invention.
- activated refers to engine operation using all of the engine cylinders.
- Deactivated refers to engine operation using less than all of the cylinders of the engine (one or more cylinders not active).
- the regenerative braking system of the present invention uses displacement on demand (DOD) in an electric hybrid vehicle to increase the current generated to recharge a battery. Specifically, if the engine is powering the vehicle and braking is initiated by an operator, cylinders of the engine are deactivated to reduce engine braking. The electric motors are able to absorb an increased amount of the vehicle's kinetic energy to produce current to charge the battery.
- DOD displacement on demand
- a vehicle 10 includes an engine 12 that drives a transmission 14 .
- the transmission 14 is driven through a torque converter 16 .
- the transmission 14 is driven through a clutch 16 .
- the engine 12 includes N cylinders 18 that are selectively deactivated during engine operation.
- engines having 4, 5, 6, 8, 10, 12 and 16 cylinders are contemplated. Air flows into the engine 12 through an intake manifold 20 and is combusted with fuel in the cylinders 18 .
- Electric machine/s 21 selectively drive or are driven by wheels 22 .
- the electric machine/s 21 drive the wheels 22 and are powered by a battery 24 .
- the electric machine/s 21 are driven by the wheels 22 to slow rotation of the wheels 22 and to produce current that is used to charge the battery 24 .
- the battery 24 communicates with the electric machine/s 21 via a voltage regulator 26 .
- the voltage regulator 26 regulates driving current from the battery 24 to the electric machine/s 21 .
- the voltage regulator 26 regulates charging current from the electric machine/s 21 to the battery 24 .
- a controller 28 communicates with the engine 12 , an engine speed sensor 30 , an intake manifold pressure sensor 32 , a brake 34 , and the voltage regulator 26 .
- the controller 28 receives a signal from the pressure sensor 32 indicative of engine load. More particularly, as engine load varies, vacuum pressure within the intake manifold 20 correspondingly varies and is sensed by the pressure sensor 32 .
- the exemplary embodiment uses manifold vacuum or pressure to indicate engine load, it can be appreciated that other methods of determining engine load can be employed.
- the controller 28 communicates with the engine to enable DOD.
- DOD occurs via deactivation of one or more cylinders 18 .
- N/2 cylinders are deactivated, although one or more cylinders may be deactivated.
- the controller 28 communicates with the engine 12 to increase the power output of the remaining cylinders 18 .
- the controller 28 continuously monitors driving conditions to selectively power the vehicle 10 electrically and/or using the engine 12 . If the conditions are proper for electric drive, the controller 28 deactivates all of the cylinders 18 and drives the vehicle 10 with the electric machines 21 in the motor mode. When the brake 34 is depressed, the controller 28 receives a brake signal. In response, the controller 28 operates the electric machine/s 21 in the generator mode to retard motion of the vehicle 10 and signals the voltage regulator 26 to charge the battery 24 using current generated by the electric machine/s 21 .
- step 100 control determines whether conditions are met for electric drive.
- Electric drive is implemented under various driving conditions. For example during vehicle acceleration, the vehicle 10 may be driven by the engine 12 . Once the vehicle is up to speed, electric drive may be implemented to maintain the vehicle at speed. If the electric drive conditions are met, control deactivates all of the cylinders 18 of the engine 12 in step 102 and signals the electric machine/s 21 to drive the wheels 22 . If the electric drive conditions are not met, control continues in step 106 to determine whether a braking condition is detected. If a braking condition is detected, control continues in step 108 . Otherwise, control ends.
- control determines whether electric drive is engaged. If not, control continues in step 110 . Otherwise, control continues in step 112 .
- control deactivates at least one cylinder 18 .
- control signals the electric machine/s 21 to be driven by the wheels 22 .
- control signals the voltage regulator 26 to charge the battery 24 using the charging current generated by the electric machines 21 .
- control determines whether the braking condition has been terminated. If not, the voltage regulator 26 continues to charge the battery 24 . If so, control activates one or more of the cylinders 18 of the engine 12 in step 118 .
- control can monitor a vehicle speed. If the vehicle speed has achieved a threshold, control activates one or more of the cylinders 18 of the engine 12 .
- the regenerative braking system of the present invention retains reduced engine braking to allow the electric motor/generators to absorb an increased amount of the vehicle's kinetic energy. Additionally, the fuel economy of the vehicle is increased as a result of the engine using less fuel during the deactivated mode.
